I'm not entirely sure how you came to the conclusion that there is some size limitation imposed by ArcGIS, but there is not. Certain formats have size limitations. Tiff comes to mind, but even the old 4gb limit has been overcome with the advent of BigTiff format which ArcGIS is capable of writing. I've been working on some hydro things since the beginning of the year, specifically processing NHDPlus v1 data for the lower 48 states. I routinely process data with ArcHydro that is in excess of 8-10GB. Outside of my hydro work, I do a lot of testing on NED data, which is several hundred GB's of data. 1GB of data is really nothing much these days.
My test machine specs:
Windows Server 2008 R2 64 bit, ArcGIS 10.1
6GB RAM
Intel Xeon W3550 @ 3.07GHz

I was told by HEC, that there is a ArcGIS limit when processing rasters.
I followed your instructions yesterday (quoted above). Today I got back on a large rawdem project using ArcHydro. Still had the stream definition and stream link "fail".** I ran AdvancedArcMapSettings.exe and found that the setting was back to 65536 instead of 1000000 like I had set it. Does this need to be reset every time?
By the way, I've been running the same tools in Model Builder on a smaller watershed and its been working like a charm.
**(The model stops after the str and strlnk grids, but they are created without projections. When I add projections and put them in the MXD, then put them in the model and link them to the next steps, i.e. two manual tasks, the rest of model finished to adjoincatchments).
Hi, I am also facing similar problem. My PC is with 4 GB RAM and I am using ArcGIS10 and ArcHydro2.0 and HEC-GeoHMS. both are not working. ArcHydro was able to calcluate Fill Sinks and Flow direction function but for flow accumulation it hanged. After closing the ArcGIS and deleting all temporary files, I rerun the flow accumulation, it gives the following message. (Pls see also attached file for detailed message).
System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIl has been returned from a call to a COM component.
I am using TIFF file and its size is 12700 col by 8500 rows. I need your help pls.

Zakir, My work around has been to NOT give up! I often (way to often) get this or other errors after attempting to create the fdr, fac, cat, str, strlnk, or cat layers (raster layers). What I do is I refresh the catalog. You will sometimes see three (3) files with the same name and different extensions. I keep refreshing the catalog view until I see the normal one file with the correct icon. I then look at the properties and see that the coordinate system is not set. I set it to what it should be, add it to the mxd and move on. This can be frustrating, and I don't know what's going on (why the error, but eventually the file is there, but it has no coordinate system) but it works.
